DotReactiveCocoa

ReactiveCocoa with dot syntax

Problem when using block to gain dot syntax

  • No code block completion suggestion
  • No type check for block parameter
  • Methods with many parameters (example: subscribeNext:error:completed:) are considered arguments for the block)
  • Can't have the same name (See ftg_concat and ftg_concatInner)
  • Can't apply to class method, as Xcode does not suggest completion for dot notation on class methods
  • Can't return instancetype (Methods like ftg_map must return RACSignal), as block return value does not support instancetype

Usage

// Only logs names that starts with "j".
//
// -filter returns a new RACSignal that only sends a new value when its block
// returns YES.
RACObserve(self, username)
.ftg_filter(^(NSString *newName){
    return [newName hasPrefix:@"j"];
})
.ftg_subscribeNext(^(NSString *newName){
    NSLog(@"%@", newName);
});
